Old Kolbe and Kolbe

Thanks for writing in. I am afraid we don't have a weatherseal quite like this. Our 58-055 is also kerf-mounted, but it is an offset bulb seal. Review the dimensions below and see if you think this could work as a potential substitute. Let me know what you think.

Thanks for verifying! That makes more sense, though the bad news is that it limits your options pretty considerably. Kerf-mount glazing bead like this isn't all that common these days. That would also explain why you're having a hard time finding it in general.

Looking through our inventory, the only glazing bead we sell that has a kerf like this is our 55-306. However, this product is explicitly designed to work in Andersen brand windows. Andersen tends to be pretty specific, so cross-brand compatibility is usually out of the question. I'm not totally optimistic that this will work for you but it may be worth considering.

I've had other customers with old K&K windows try our 55-164 as a potential alternative, but I've never heard many successful reports back. All the same, I thought I'd mention it as another alternative to consider.

Sorry again that we couldn't offer you anything better! These windows are fairly old so it's tough to get old glazing like we used to.
